Button System

For Fixation of Acromioclavicular Separations Due To Coracoclavicular Disruption.

Infinity-Lock Button System is a permanent implantable device for stabilization of acromioclavicular joint separations, comprising a 7 mm x 240 mm Tube-Tape and 4 mm x 12 mm titanium alloy Button supplied together with disposable cannulated drill bit and guidewire.

  • Strong: system strength 1014 N

  • Low stretch under cyclic tension

  • No more coracoid drilling

The Tube-Tape has a loop at one end which is passed under the coracoid process by a lead suture; the other end of the tape is then fed back through this loop to provide distal fixation. Superior fixation is achieved by passing the end of the tape through a bone tunnel in the clavicle and securing it with the titanium Button. A coracoid passer, such as the Xiros CC-Hook, is also required.


Infinity-Lock Button System is indicated for patients with acromioclavicular separations resulting from disruption to the coracoclavicular ligaments.

How Does It Work?

  1. The implant is passed around the coracoid process and both limbs are passed through the loop
  2. Both limbs of the Tube-Tape are passed through the 4 mm diameter bone tunnel one at a time
  3. Single low profile button is used to anchor the Tube-Tape to the bone
  4. Secured with a surgeon’s knot inferiorly, or anteriorly if insufficient space below the clavicle

Product Documents


  • Known hypersensitivity to implant materials. If the patient is suspected of having any foreign body sensitivity, appropriate tests should be made prior to implantation.
  • Infections or any structural or pathological condition of the bone or soft tissue that would be expected to impair healing or secure fixation.
  • Patients unable or unwilling to restrict activities to prescribed levels or follow a rehabilitation program during the healing period.
  • Skeletally immature patients are not suited as the Infinity-Lock will not elongate with growth. The use of this medical device and placement of hardware or implants must not bridge, disturb, or disrupt the growth plate.
